I took the advice and achieved next to nothing.

The score is that my daughter's "upteen-thousand dollars Mac" has no 
problems in finding and reading the content of my ($2.00) SD-Card 
reader.  My computer - even with the help of the usb-hub - cannot find 
it.  The red light on the plugged-in SD-Card reader is on, but there is 
no trace of it under the /media directory.  And I do not know where else 
to look. 

The second output of dmesg (attached) remained unchanged when I ran the
"mount" command.  However, my computer was not able to read the contents
of the "memory stick" until it received the "mount" command. 

Buying a new computer seems a drastic remedy?
